Amphibian Diversity, Abundance and Temporary Breeding Habitats in the Morgan Arboretum

Amphibian Diversity, Abundance and Temporary Breeding Habitats in the Morgan Arboretum

We are the @ColdBloodedHopsters, a group of McGill students in the class St Lawrence Ecosystems (ENVB222) studying amphibians at the Morgan Arboretum. Make sure to follow us on Twitter for more updates on our research! Introduction: Although they only occupy 0.5% of all animal species, amphibians are a large and diverse group with over 6000 […]

Variation in the abundance of the red-backed “soil-amander”-Amphibians of the Morgan Arboretum

Introduction Nature is full of environmental and biological interactions. Some well-known, like how temperature and precipitation determine vegetation in different environments. Others are less obvious, and require keen observation to see. Last month, in the Morgan Arboretum, we looked at one of these subtle changes: how changing soil types affect the presence and abundance of […]

Salamanders belong to the Caudata order. Along with Anura (frogs) and Gymnophiona (caecilians), they belong to the Amphibian group (Bishop 1943). Salamanders are often confused with lizards because of their similar body form but they lack scales. Instead salamanders have moist glandular skin that is permeable to water and unlike frogs, they have tails and […]
